In assessing its technology
needs, the client made a decision
to move this system to less
expensive x86 servers. Because the
replacement system was unable to
meet performance requirements,
the company experienced an
incident where the online booking
system was down for four hours,
hundreds of flights were canceled
and a significant amount of
revenue was lost.
The client replaced the failing
online booking system with six
Power Systems S822Ls, three
FlashSystem 840s, DB2* and Red
Hat Enterprise Linux. The new
system finished certain processes
in 10 minutes, compared to two
hours with the previous system.
It ran reports in 15 minutes
instead of six hours. Initial
software costs were reduced by
$1.6 million. The company gets
the performance, reliability and
availability that it needs.
Thanks to its move to a
Power Systems platform, this
client is well-positioned to meet
current and future analytics
and big data needs. It's able to
offer more customized services
to travelers, which boosts
customer loyalty. The company
now has a competitive edge as it
can sift through data quickly to
"Choosing a system based largely on cost may
not be the best decision. Low-cost solutions don't
always save money, and, in many instances,
will end up costing you money."

Hamm Reno Group
Germany's Hamm Reno Group
(HR Group) is the second largest
shoe retailer in Europe with more
than 2,000 points of sale in 20
countries. Managing inventory
and forecasting market demand
are critical to maintaining profits.
In 2012, the retailer decided
to employ SAP HANA on a
Lenovo x86 platform, the only
option available at that time.
But HR Group found x86 had
poor virtualization, lackluster
performance and wasn't flexible.
In 2015, when SAP HANA
became available for POWER, HR
Group installed a Power Systems
S822L server for production,
and a S824 server for test and
Origins of Chip Wars
Competition between Intel* x86 and IBM POWER* for market share began
decades ago. Intel introduced its first microprocessor in 1978. The IBM
Power Systems* architecture made its debut in 1990 in the form of the
RS/6000*. The rivalry intensified during the years when the workstation and
server markets were the driving force for platform selection.
The term "chip wars" originated with Gordon Bell, the vice president of
engineering at Digital Equipment Corporation. In 1993, Bell wrote a paper
titled "Chip Wars: Handicapping the Six Leading Microprocessors." The six
were Digital, IBM, Intel, HP MIPS Technologies and Sun Microsystems.
Bell's theory was that by 2000, the six would become three: Intel x86,
IBM POWER and MIPS. Only x86 and POWER made it into the 21st century.

Power Systems servers have the
capability to handle open-source
databases without compromising
performance. That's exactly what
a large North American retailer
needed in order to handle a
hybrid open-source database
This client uses DB2/Linux/
UNIX*/Windows* for its SQL
requirements and MongoDB
and Redis Labs for its NoSQL
applications. However, the
retailer found a batch application
used to reconcile thousands
of individual product records
between MongoDB and the
primary DB2 database on its
mainframe was consuming all of
the available cycles on x86.
